I want to install one on my car, and would like to know how well the factory one works. Maybe someone has a oil temp guage and could tell me how much the cooler actually lowered the oil temp. I have posted this on another board with no response, so I guess no one knows the answer to my question. Hopefully someone here can shed some light on this subject.

 

Sorry, don't know

I think I may have heard it lowers the temp by 10* but I'm not positive. It also serves to warm the oil in the winter I think. If I were going through the trouble of installing one I would get an aftermarket brand, probably much more effective.

 

I know I removed mine when I rebuilt my engine, and the car runs very very cool. With a 160 stat... it usally stays around 160 So I dont think it really helps too much.

 

I doubt its very effective. Dont know if you have seen one, but it uses coolant in a plate between the oil filter and block to cool the oil down to the temperature the coolant is at. Its not like a thing where the oil spends much time as it passes through there either, its rather quick, so I dont see how it can be all that effective as compared to a true oil cooler, one that has its own little radiator.

 

I saw the setup on my friends GTA, he doesn't like it at all, and wants to get rid of it. I figure its got to be better than nothing, but maybe I should look into a cooler that works a little more effectively.

Thanks for the input.

 

Don't be fooled my the compact size of the oil cooler, they can be very effective in controling peak oil temperatures. Notice I say peak. Similar design coolers are used on 5.0L Mustang police packages. What's trying to be accomplished is controlling maximum oil temperature under worst case operating conditions. Worst case would mean sustained high (engine) speed, high ambient conditions.
Also, consider this, & assume no oil cooler. High coolant temperatures can raise oil temperatues, but high oil temperatures won't really affect coolant temperatures. Due to the hi-perf nature of the car, coupled with the 3rd gen's higher than conventional coolant temperatures, dictates the use of an engine oil cooler. Rule of thumb for oil temps: for every 10 degree F the oil temp goes over 250 F, the oxidation rate of the oil doubles.

It sucks dude. Just get an aftermarket one! Besides were not taking it out this weekend any way. Cheap skate, college people. JK LOL

I have heard horror stories of engines being destroyed due to the stock oil cooler. Basically, over time, the stock cooler's fins get plugged. This yields a higher than normal oil pressure condition that allows you to think that your pressure is good. But, in fact, the pressure at the bearings is terrible. Although this isn't a well known problem I have heard of it happening to 2 people so far.

Anyhow - you need to remove it in order to install Hooker SuperComp full length long tube headers :-)
